Electric cables - Low voltage energy cables of rated voltages up to and including 450/750 V (U0/U) -- Part 3-41: Cables with special fire performance - Single core non-sheathed cables with halogen-free crosslinked insulation, and low emission of smoke
EN 50525-3-41 applies to non-sheathed single core cables insulated with halogen-free crosslinked compound and having low emission of smoke and corrosive gases when exposed to fire. NOTE 1 Low emission of smoke is checked in accordance with EN 61034-2. Low emission of corrosive gases is checked as part of the check for absence of halogens (see Annex B of EN 50525-1). The cables are of rated voltages U0/U up to and including 450/750 V. NOTE 2 Cables rated 450/750 V may be used at 600/1 000 V when this cable is used in fixed installations with mechanical protection, within switchgear and control gear - see HD 516. The cables are intended for fixed wiring applications. The maximum conductor operating temperature for each of the cables in this standard is 90 °C. NOTE 3 HD 516 contains extensive guidance on the safe use of cables in this standard. This EN 50525-3-41 should be read in conjunction with EN 50525-1, which specifies general requirements.
